Toalt whom t may camera,.-y

Be it known that LLHENRY LEGER, of

Bostem-in -the county of Suffolk and-State of Massachusetts, haveinvented certain new and useful Improvements in Miter-Boxes, of whichthe following is a specification:

This invention relates to miter boxes,-and more particularly to foldingmiter boxes.

The object of the invention is to provide a miter box which has a .widerange of capacity, 'which canbe adjusted to cutl any. de-

`slred angle, Which has provisionffor' cushionadapted to be mounted onaWooden horse or,

to occupy a comparatively smallspace.

Accordingly, a Y feature of-the invention contemplates the provision ofa miter box having a Work rest or vertical face-plate any other suitablesupport. This work rest may be provided with extensions hinged theretoand 4adapted to be folded up out oir'v Uthewayfor transportation, orlowered to produce a long back or vertical support for the materialwhich is to be Jsawed.,

,A Vfurther feature of the. invention contemplates the provision ofmeans for var vi lng the height of the saw, as by a telescop`v inglstructure, and, this structure may be utilized for pneumaticallycushioning the saw. 1

A vfurther feature Acontemplates the Y provision of means for securingthe saw guidel so that any angle be cut; -In its present embodimentmeans'are prov'ded for locking the guide automatically at 'themorecommon angles, which locking means can p be released bymeans-operated bythe saw,

and means are also provided for clamping the saw guide in any Otherfeatures of the inventionwi'llbe referred to in connection with thespecific description of. the illustrated embodiment of the invention.

The several-features -of the invention will be clearly understood from.an inspection of the accompanying 'drawings and the following detailed'description of the construction shown therein.

In the drawings Figure 1 is a plan view of the miter box with a saw inposition for cutting a board at right angles to its length,

Fig. 2 is a side elevation of the same, Figl b 2a is afragmentary viewof the locking egree of singularity.-

'and tripping'mechanism, 3 is a- .sec-

tional front, elevation taken on the line 3 3 in. Fig. 2, Fig. 4 is aside elevation'of themiter-box `in folded position, Fig. 5 is a verticalsection taken on the line 5 5 in Fig. 3, showing-the telescopicstructure in extended position, Fig. 6 is a horizontal section on anenlarged scale taken on the` line 6 6 in Fig.v 5, Fig. 7 is afragmentary -side elevation of a modified form of saw guide, Fig. 8 isanend elevation of thesame,

and Fig. 9 is a. detail/sectional View ofthe pneumatic cushioncontrolling device.- Y

As yillustrated'in thel drawings, the device comprises va work rest 10,having'a .front or work-engaging `face formed by the finished faces ofribs 12. .The-lower edge ofthe Work rest is provided with afiinishedface 14, whichis at right angles to the Work-engaging face l2. The workrest is formed VWithtwo vertical-sections separated by a slot 16 throughwhich the-blade 18 ofthe saw can pass. The vertical sections are joinedto an offset bar 20, which 'also hasa finished v-front face. The offsetbar is adapted .to be clamped to any suitable support 22, having a flatupper face for` engagement by the face 14. AThis support maybe a woodenhorse, a=plank, a bench, orany other 'suitable support. The device isclamped to said support by means of hooked 4screws 24 having laterallyprojecting fingers 26, whichengage the under side of the support 22, Thethreaded stems of the screws pass lthrough bosses 28 on the rear of thecrossbar and enter nuts 30, which bear against the upper ends vof said'bosses Screws 31 may beprovided, having their ends'pointedandprojecting below the finished surface' 14 to' enter the top surfaceofthe' support' Patented Dec. 10, 1912.

to which 'the device is attached. 'By this with ribs es; havingfinished' faces which are in the plane ofi the faces of the ribsicprevent the' escape of air therebetween, and

are' adapted 'to be held in adjusted position by knurled clamping screws48. A periphe'ral groove,50 is formed in the exterior of' eac-h plunger,which is adapted to receive the inwardly projecting ends 52.0f a wirespring 54. These springs lie in grooves near the upper ends ot thesockets 40; 42, and the ends 52 prevent the accidental withdrawal of theplungers from their' sockets,

as shown. in Fig. 5,

Slidably mounted within the plungers 44 an'd 46, are plungers 56 and 58,respectively,

having their upper ends secured in a crossbar 60, by means of .threadedcaps 62. Ther plungers 56 and 58 tit the plungers 44 and 46 so vasltoprevent escape of airtherebetween, and are adapted tobe held in adjustedposition by means of screws 64. 'The plungers' 56 and 58 are hollow andare provided with screw threaded plugs66 in theirv lower ends, saidplugs'havinga central passage 68. Theupper ends 'of thev plungers 56 and58 are vprovided= ;-with air passages 70 and .72, 'respectivelwhichcommunicatewith an air passage '74 extending 'entirely through thecross-'bar' 60, and. also' with similar passages v76, 78,`respegztively, communicatr'ng 'with the .external atmosphere."1

The passa' es 76 and 78 are adapted to .be controlled y screws 80 and82, respectively.' Thus a pneumatic 'cushion-for '.the saw4 is formedwithin the telescoping structure, which can be controlled' bA either ofthe screws 80 or 82. 4By regu atin' either ofA said screws sc thatlthere'is o yfa slight air discharge throughf'the `correspondmg passage,the weight with .which .the saw.

bears upon the material being sawed can j be regulated so thattheylatter will not-be torn or splintered. -Although two regu1atingscrews are shown, it will be understood that only one need be employedfBy means of the aboveteles'eoping structure, the vertical capacity ofthe device is greatly increased. 4

The sawiding means comprises an arm 84 pivoted I); a screw 86 ,in a bosson the cross-bar 60. A stud 88 is secured in the arm 84 bya set screw89, and depends therefrombetween the sockets 40 and 42. :Said

1,046,6 is l embracesthe-rod 126 and is hel 'tendin l c .one -o theholes 122, and automatlcally stud is-provided. with a slot 90 to receivethe blade 18' andthe back- 19' of the saw,

the lower edge of the back being adapted to rest on the shoulders formedin the slot- 90. The arm 84 is bifurcated to provide bars 85 and 87,which straddle and are adapted to bear against a sector-shaped web 92,having van arcuate slot 94. A' clamping screw 96 on the arm 84 passesthrough the slot 94 and is adapted to clamp the bars 85 and 87.againstthe web 92 to hold thc saw at any degree of angularity as determ'inedbyAthe protractor 98 mounted adjacent" to the slotf94.

.livctally mounted-in ears 100 on4 the arm 84 is an arm 102, whichforms' an extension of the arm 84 and carries the from: stud of the sawguide. In the embodiment shown in Figs. 1, l 2 and 4,' thusstud 104 isslotted similarly to the' stud 88, and is held remova'bly in the outerend ofv -the arm 102 by a knurled nut 106. 'Ihestd 104 is cut 4away at108 to -clear the-endcof the bar 87,l

as shown in Fi' 4.4 When it is desired to fold -up the device, the stud104-is removed' from the outer end of the arm 102, the arm.- isthen'swung oyer into the 'position shown in Fig'. 4, and the stud isinserted as shownf vin thls ligure and secured by the nut. 106;` "Ihehead of ascrew 1120,'carried 'by a plunger 112 to be hereinafter'described, pro- 'jects into the-enlarged portion of lthe ,saw

'guiding 4slot, yand when the nut 106 is screwed down tightlyto drawvthe stud upv into position,l this screw head prevents the, arm fromSwingin upward.

loo

In a modified orm, the stud 104 is rejplaced'by al stem 114, pivotedbetween ears 5116 on 'a'n arx'n- 118 similarto the arm 102,4`

and 4clamped by d iscrew 120.

In prder to automatically lockthen saw 'guide in any one of the..- morelcommon angles, such as 10', 22.5, 30", and 45, I provide a. plunger11'2, which is adaptedto entergany on of the holes 122-formed in the.sector-shaped web- 92. .-"A rod 126 is `slidably mounted in e'ars`t128and.'130 on the side of the arm/84, and is provided with a laterallyprojecting ltinger 132- which is Y connected' to' the 'plunger 112 bythe screw 110, The plunger 112 is s lidably mounted 'm a lug :113projecting upwardfr'om the endl 'of 'the bar 87. A coiled 'spring 134between a" pin 136 onlsaid'rod and the ear 130, thus normally to keepthe plunger in pushing said plunger' into one of said holes whenever.-the former comes .opposite one of the latter. A i

In order to release the saw guide, I provide a tripping shaft 140, onthe side of the bar 102. This shaft is `provided at one end e path ofthe,

with a laterally projecting lui 146, which is' -idapted to be broughtinto t opposing endof the'lrold .afterif'tliirnuf 102"has` been swungupfintd thev position'v Thisfis accomplished by shounin Fig. 2a.A yraisingthe handle .of thesawr "'A knob 1,48

' 5 isA provided atl the opposite endof said shaft,

ula-nbr the latter'may be moved m'anually, l.4 but .when the arm 102 isswung upinto the'.

position indicated in this ligure theknob anddlug on the shaftcause thelatter to r0- 'tale partially automatically so that the lug i-lt dropsinto position opposite the end of the rod 126. Then when the saw and thearm are lowered into horizontalposition, t-he lug engages the end ot'the rod 126 and i -pushes-tl1e latter to draw the plunger 112 from theweb 92 and release the arm 8l so that'the saw can be swung in anydesiredA direction. Then it is desired to release the plunger to-lockthe arm Si, the knob 148 I is grasped and the shaft 140 rotated slightlyto swing the' lug 146 outA of the path of the rod 1.26, whereupon theplunger is free to enter any one of the holes y129, which it Will j doas it is brought opposite the same. When it is deslred to secure the sawguide at any 3o tal position, the latter can be swunfr to anvintermediate p oint'vitis clamped by means of the screw 96.' When theclamping screw -96 is released and the plunger is held by the trippingshaft with the. saw in horizonposition within the capacity pf the deviceas indicated by the'protracto98.
